SEO Editor

Write with the scoreboard already on the page.

Semurai's SEO Editor puts the content score, structure targets, term coverage, live SERP competitors and an in-editor AI agent next to your draft — so you fix the article while you write it, not after review.

Inside the editor

Six panels. Every one earns its place.

This is the actual editor interface — here is what each panel does and why it is there.

01
51/100

Suggested 77+

Content score

A live 0–100 score for how completely the draft covers the topic. The marker shows the score the currently ranking pages average, so you always know what "good enough" means for this keyword.

02
Words 2,006 2,914
Headings 7 36
Images 0 8

Structure targets

Words, headings and images measured against the top-ranking pages. A thin 2,006-word draft against a 2,914-word benchmark is a gap you can see before you publish, not after.

03
ai seo tools 16 / 12 content optimization 46 / 15 keyword research 0 / 7 content score 4 / 6 serp analysis 0 / 5

SEO terms

Recommended and related terms with a used / target count each. Colour tells you instantly what is covered, what is thin, what is missing and what you have overused.

Competitors

The pages ranking right now, with word counts, titles, meta descriptions and expandable heading outlines — so your structure decisions are informed, not guessed.

05
Current draft

Ask about the current draft.

Ask AI

A Content Agent that already has your draft as context. Review a section, tighten structure, fix tone, or select text and describe the edit you want inline.

06
Meta Title & Description missing
Auto-Optimize

Checks & Auto-Optimize

Concrete issues like a missing meta title surface as one-click fixes. Auto-Optimize drafts the improvements, and you approve them before anything changes.

Term coverage

Stop guessing whether a keyword is "in there enough".

Each term carries a used / target count pulled from what actually ranks. The colour is the instruction — you never have to interpret a density percentage again.

  • On target Covered at the depth top results use.
  • Thin Present, but under the benchmark.
  • Overused Repeated well past a natural range.
  • Missing Not in the draft yet.

Auto-Optimize

See the rewrite before it touches your article.

Auto-Optimize finds the weak passage, drafts a stronger version and shows you both. Nothing replaces your text until you press apply.

  • Every suggestion names the issue it is solving
  • Side-by-side before and after, with the score impact
  • Apply, edit or revert — the decision stays yours

No copy-pasting into a separate chat window. The Content Agent works inside the editor with your article, keyword and score as context.

  • It reads the live draft, keyword and score — no re-briefing
  • Answers arrive as suggestions you accept or discard
  • Selection-scoped edits keep the rest of the article untouched

FAQ

Common questions

Is this just another AI writer?

No. The AI is one panel out of six. The editor is built around measurement — score, structure targets, term coverage and live competitor data — so you can judge a draft objectively whether a human or the agent wrote it.

How is the content score calculated?

It reflects how completely the draft covers the topic compared with the pages currently ranking for your keyword: term coverage, structure depth and readability. The suggested target is derived from those same pages, so it moves per keyword.

Will Auto-Optimize change my article on its own?

No. Auto-Optimize drafts improvements and presents them for review. You approve, edit or reject each one, and nothing is published without your decision.

Can I use it on existing content?

Yes. Bring in an existing article, and it is scored against today's search expectations rather than the ones it was written for — which is usually where the fastest wins are.

Does it work outside English?

Yes. Targets and competitor data are pulled per keyword and market, and the editor includes translation for moving a finished article into another language.

Give your next article a real review before it ships.

Open the editor, paste a keyword, and see the score, targets and gaps in under a minute.
